A first spring 10 is fixed to the top of the insulating outer rod 2, and the top of the first spring 10 is located below the bolt tightening mechanism. The insulating inner rod 3 passes through the first spring 10. Due to the setting of the first spring 10, the sleeve of the bolt tightening device is always aligned with the wire clamp nut due to the restoring force of the first spring 10. A limiting ring 15 is provided at the lower part of the insulating inner rod 3 to increase the safety of the operator. A hexagonal screw hole with an opening downward is provided at the bottom of the insulating inner rod 3 to facilitate tightening the bolt with an electric wrench.

[0022] The lead fixing mechanism 4 includes a connecting frame 5 movably connected to the front side and rear side of the wire clamp fixing frame 1, an axe-shaped fixing frame 7 fixedly connected to the right end of the connecting frame 5, and a connecting rod 6 movably connected to the left end of the connecting frame 5.

The unlocking rope 8 is fixed to the top of the connecting rod 6, and the other end of the unlocking rope 8 is fixed to the locking mechanism 9. When the J-type wire clamp needs to be fixed, the connecting rod 6 is pulled downward, and the connecting rod 6 drives the connecting frame 5 to rotate upward, and the right end of the connecting frame 5 drives the axe-shaped fixing frame 7 to move upward, thereby fixing the J-type wire clamp to the top of the wire clamp fixing frame 1. At this time, the locking mechanism is in a locked state.

[0023] The bolt fastening mechanism includes a support plate 11 fixedly connected to the top of the insulating inner rod 3, a bolt fastening sleeve 12 fixedly connected to the upper surface of the support plate 11 by welding and matched with the bolt of the J-type wire clamp, a limit frame 13 is located above the support plate 12, and the front and rear ends of the right side of the limit frame 13 are movably connected to the front and rear side surfaces of the wire clamp fixing frame 1 through a pin shaft.

At this time, the limit frame 13 moves upward and pushes the bottom of the wire clamp, so that the upper and lower parts of the wire clamp are staggered to clamp the wire.

[0024] A through hole is provided at the top of the wire clamp fixing frame 1 for the top of the J-shaped wire clamp to pass through, and a limit cover 14 is provided at the top of the through hole. The setting of the limit cover 14 prevents the bolt on the J-shaped wire clamp from moving upward all the time. An adjusting bolt 16 for adjusting the size of the through hole is provided on the left side of the through hole, so as to adapt to the sizes of different wire clamps. The sizes of different wire clamps can be adapted by adjusting the length of the bolt at the top of the wire clamp fixing frame.

[0025] The specific operating steps are as follows: 1. Put the wire to be connected into the wire clamp; 2. Put the wire clamp connected to the wire to be connected into the wire clamp fixing frame 1; 3. Pull the connecting rod 6 downward, the axe-shaped fixing frame 7 moves upward and drives the wire to be connected to move upward, so that the wire to be connected and the upper part of the wire clamp are fixed on the wire clamp fixing frame 1, and the locking mechanism 9 is in a locked state at this time, so that the axe-shaped fixing frame 7 and the lead wire are clamped in a state; 4. Hold the insulating outer rod 2 and move it so that the upper clamp of the wire clamp clamps the main wire; 5. Push the insulating inner rod 3 upward so that the bolt fixing sleeve 12 is stuck in the nut of the wire clamp; 6. Rotate the insulating inner rod 3 upward, tighten the wire clamp bolt, so that the wire clamp clamps the wire and fixes the wire clamp and the wire; 7. Operate the locking mechanism 9, move the connecting rod 6 upward, loosen the axe-shaped fixing frame 7 from the wire clamp and the wire, remove the wire clamp fixing frame, and the operation is completed.

A first spring 10 is fixed to the top of the insulating outer rod 2, and the top of the first spring 10 is located below the bolt tightening mechanism. The insulating inner rod 3 passes through the first spring 10. The arrangement of the first spring 10 ensures that the sleeve of the bolt tightening device is always aligned with the wire clamp nut due to the restoring force of the first spring 10. A limiting ring 15 is provided at the bottom of the insulating inner rod 3 to increase the safety of the operator.

The left end of the connecting frame 5 is movably connected to the top of the connecting rod 6 through a pin shaft. The unlocking rope 8 is fixed to the top of the connecting rod 6, and the other end of the unlocking rope 8 is fixed to the locking mechanism 9. When the J-type wire clamp needs to be fixed, the connecting rod 6 is pulled downward, and the connecting rod 6 drives the connecting frame 5 to rotate upward, and the right end of the connecting frame 5 drives the axe-shaped fixing frame 7 to move upward, thereby fixing the J-type wire clamp to the top of the wire clamp fixing frame 1. At this time, the locking mechanism is in a locked state.

[0029] The bolt fastening mechanism includes a support plate 11 fixedly connected to the top of the insulating inner rod 3, a bolt fastening sleeve 12 fixedly connected to the upper surface of the support plate 11 by welding and matched with the bolt of the J-type wire clamp, a limit frame 13 is located above the support plate 12, and the front and rear ends of the right side of the limit frame 13 are movably connected to the front and rear side surfaces of the wire clamp fixing frame 1 through a pin shaft. The support plate 11 moves upward and pushes the limit frame 13 to move upward to move the J-type wire clamp. The bolt fixing sleeve 12 opens upward, and at this time, the insulating inner rod 3 is pushed upward to move upward, so that the bolt fastening sleeve 12 is sleeved on the bottom of the bolt of the J-type wire clamp, and the insulating inner rod 3 is rotated to drive the bolt of the J-type wire clamp to rotate. At this time, the limit frame 13 moves upward and pushes the bottom of the wire clamp, so that the upper and lower parts of the wire clamp are staggered to clamp the wire.

[0030] A through hole is provided at the top of the wire clamp fixing frame 1 for the top of the J-shaped wire clamp to pass through, and a limit cover 14 is provided at the top of the through hole. The setting of the limit cover 14 prevents the bolt on the J-shaped wire clamp from moving upward all the time. An adjusting bolt 16 for adjusting the size of the through hole is provided on the left side of the through hole, so as to adapt to the sizes of different wire clamps. The sizes of different wire clamps can be adapted by adjusting the length of the bolt at the top of the wire clamp fixing frame.

The left end of the locking rod 18 is connected to the left side of the sleeve 17 through a second spring 20. The left end of the locking rod 18 is provided with a handle 19, and the handle 19 is connected to the top of the connecting rod 6 through the unlocking rope 8. The first locking groove 21 and the second locking groove 22 are both opened to the left. A through groove for the locking rod 18 to pass through is opened on the left side of the sleeve 17, which is convenient for the up and down movement of the locking rod 18. When needed, the connecting rod 6 moves upward and keeps the axe-shaped fixing frame 7 fixed to the lead wire, that is, the locking rod 18 is pulled out to the left, so that the right end of the locking rod 18 is separated from the second locking groove 22, and while pushing the connecting rod 6 upward, the sleeve 17 moves upward synchronously with the connecting rod 6, and the locking rod 18 moves upward synchronously with the sleeve 17. When the locking rod 18 moves to the position of the first locking groove 21, due to the action of the second spring 20, Push the locking rod 18 to the right so that the locking rod 18 is located in the first locking groove 21, then the position of the sleeve 17 and the insulating outer rod 2 remains unchanged, and the connecting rod 6, the connecting frame 5 and the axe-shaped fixing frame 7 are kept fixed in a fixed state. When the axe-shaped fixing frame 7 needs to loosen the lead, while pulling the connecting rod 6 downward, the sleeve 17 and the connecting rod 6 move downward synchronously, and the locking rod 18 and the sleeve 17 move downward synchronously. When the locking rod 18 moves to the position of the second locking groove 22, due to the action of the second spring 20, the locking rod 18 is pushed to the right so that the locking rod 18 is located in the second locking groove 22, then the position of the sleeve 17 and the insulating outer rod 2 remains unchanged, and the lead and the wire clamp of the axe-shaped fixing frame 7 are loosened.

[0032] The specific operating steps are as follows: 1. Put the wire to be connected into the wire clamp; 2. Put the wire clamp connected to the wire to be connected into the wire clamp fixing frame 1; 3.
